针对信息系统存储量越来越大的情况,提出采用分布式数据库技术,通过建立转移信息索引表和对数据进行水平分片来实现历史数据的转移和恢复,从根本上解决了信息存储不断增加对系统速度的影响,同时提供了应用软件访问的透明性,也很好地保证了历史数据的查询访问速度,为大数据量信息系统设计提供了一种解决方法。
The Distributed Database technology has been adopt that can get the solution of more and more storage of the information system. As the usage of transfer information index list and data horizontal fragment technology, the problem between the increasing storage and system running speed has been served smoothly from the source. At the same time, it provides a solution for the mass storage information system with a high speed searching with history data and transparency access operation to application software.
